The U.S. International Trade Commission ruled that NVIDIA's chips infringe on three memory controller related Rambus patents. The ruling forces NVIDIA to pay license fees to Rambus, as non-compliance would lead to an import ban of most of NVIDIA's products. NVIDIA said it plans to appeal the patent ruling.
A judge with the ITC said in January that Nvidia was infringing three Rambus patents, while two other patents were ruled invalid. In its announcement yesterday, the commission sided with the judge on the three patents.
It ordered the parties to post a bond of 2.65 percent of the value of the imports to continue bringing the products into the U.S. during the presidential review period.
The patents relate to controllers that connect the memory and the graphics chips. The complaint targets Nvidia’s GeForce, Quadro, nForce, Tesla and Tegra lines.
